How quickly he is developing. Just imagine that until 2-3 years ago, he was a reserve player at Metz, in the third tier of French football...
In June he nearly signed for APOEL... He missed-out on a Champions League opportunity, but he succeeded in making a name for himself in the Premier League.
Even though he has already represented Senegal at international level, he can still choose France.
He may not be available for the next games of France, due to injury, but if he continues like this, he will be called-up for sure. At the moment, Giroud is injured at least until January, but anyway Sakho maybe is already better than him.
Diafra isn't a player than will have a fantastic game, or create fancy stuff and opportunities like Enner Valencia does.
He is an intelligent forward, who can make the difference at 1 or 2 moments of the game.
His Header Accuracy can rise to about 82-83, and maybe his Jump to 80.
Also, hasn't he played out-wide for West Ham?
